Maybe we should hang on and see if Kaz can shed some light on the subject.

Ahh Tsuchiya, of course

I have the Best Motoring title (VTEC Club #1) where his own modified NSX-R races a standard NSX-R. At that point he claims no engine mods for his car and indeed those extra ignition leads aren't there. There's very little if anything between the performance of the 2 cars.

I almost agree with you AR but it's a law of diminishing returns. You can't simply add up all the gains each individual change makes. I'd suggest that if a car with I/H/E mods makes 300hp, adding free flow cats and a remap might give you another 10hp, maybe less?

We'll soon know (hopefully) what free flow cats do for a 3.2 Ltr already fitted with a decent exhaust

We need to get Fusilov's NSX-R on the TDI rollers to see what a genuine NSX-R engine really adds... if anything

Cheers
